Noob needs current tutorial please

[Duke Normandin]

Hello & Happy New Year!

I'm new to Chicken Scheme. I've got some exposure to newLISP and
Gambit-C. I'm continueing my test-drive of Chicken because it
produced the smallest executable for helloworld.scm.

However, I'm having a bitch of a time finding a tutorial with
example code that is current to the most recent version of Chicken.
For example: at http://wiki.call-cc.org/friendly-chicken
one of the examples is:

#;1> (use utf8)

It barfs up:

Error: unbound variable: use

        Call history:

        <syntax>          (use utf8)
        <eval>    (use utf8)    <--

and the list goes on!

Any recent tutorials for Chicken out there? TIA ..
